 private static bool is64BitOS
        {
            get
            {
                string is64 = (string)Registry.LocalMachine.OpenSubKey(@"SYSTEM\CurrentControlSet\Control\Session Manager\Environment", false).GetValue("PROCESSOR_ARCHITECTURE", false);
                if (is64 != "x86")
                    return true;
                else
                    return false;
            }
        }

Usage:

Code:

  if (is64BitOS)
              MessageBox.Show("x64");
            else
                MessageBox.Show("x86");
